Forza model B4-FPexhaust controller


The Model B4-FP controller is a 2-way exhaust controller that is designed for installation in extreme environments as one would encounter in the engine bay of high performance sports cars.

Although similar to the Model B4, the B4-FP is specifically designed for use in motor cars such as the Ferrari 488 Pista and other motor cars with very sensitive vacuum control technologies.  The Model B4-FP installation kit includes two additional vacuum control valves so that the electrical circuit for the controller is completely separate from the circuit controlling the existing vacuum control valves.  This design allow control of the exhaust bypass valves without any error conditions or trouble codes.  And, as is the case with the Model B4, you can choose the Normal or Always Open mode at vehicle start.

The Forza Model B4-FP Exhaust Bypass Valve Controller provides two different operational modes — both modes can be selected using the included remote transmitter or a manual On/Off switch.

  1. Normal Mode:  In this mode, the vehicle controls the operation of the exhaust bypass valves.  This is the stock operation.  You can choose this as your start-up mode.
  2. Always Open:  Selecting this mode will force the exhaust bypass valves to the open position — and remain open.  When the valves are Always Open, you have the full experience of hearing your engine exhaust at any time.  You can also choose as your start-up mode.
